For the past two years, the fleets who responded to
the oil study named Shell Rotella the oil brand they are

Exxon Mobil Delvac and Chevron Delo, respectively,
also made the top three in oil brands fleets were most
familiar with and used most frequently.

oil preference results.
In a previous Fleet Maintenance oil study Castrol was the
second most used engine oil by fleets, coming in just
below Shell Rotella. While Castrol is still one of the top
five engine oil brands used by fleets, its popularity in the
industry went down to 12 percent, compared to Shell
Rotella (42 percent), Exxon Mobil Delvac (26 percent) and
Chevron Delo (20 percent).

list for most used synthetic engine oil, but in the most
recent study – according to the survey respondents who
indicated they use synthetic engine oil (56 percent), Shell
Rotella took the top spot. Exxon Mobil Delvac ranked
second and Castrol placed third.
